MP2481DH - 1.4MHz White LED Driver

Download the MP2481DH datasheet PDF. This datasheet also covers the MP2481 variant, as both devices belong to the same 1.4mhz white led driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The MP2481 is a 36V, 1.2A, white LED driver suitable for either step-down or inverting step-up/down applications.

It achieves 1.2A peak output current over a wide input supply range with excellent load and line regulation.

Key Features

  • 1.2A Maximum Output Current.
  • Unique Step-up/down Operation (Buck- Boost Mode).
  • Wide 4.5V to 36V Operating Input Range for Step-Down.

The Future of Analog IC Technology MP2481 36V, 1.2A, 1.4MHz White LED Driver DESCRIPTION The MP2481 is a 36V, 1.2A, white LED driver suitable for either step-down or inverting step-up/down applications. It achieves 1.2A peak output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes thermal shutdown, cycle-by-cycle peak current limiting, input over voltage protection, open strings protection and output short circuit protection. The MP2481 incorporates both DC and PWM dimming onto a single control pin. The separate input reference ground pin allows for direct enable and/or dimming control for a positive to negative power conversion.
